The Propilot safety system shuts down after 40 miles. Nissan has sent out a super technician and states there is no cure. This has gone on since I purchased the vehicle over a year ago. Nissan still has no cure. The Propilot system utilizes cameras and radar to maintain a safe distance from the vehicle ahead and keep the vehicle centered in its lane. Hi Chris, We drove the Rogue to Larned Saturday from McPherson on [XXX] . The cruise control shut off 4 times. Forward driving aids disabled. It took 5 to 10 miles each time to reset, then it worked without stopping or turning off the car. There was a lot of traffic and there are several towns we went through. I don’t think the sensors were bored from a plain path. The sensors were not dirty. Does Nissan have a cure for this? Thanks, [XXX] This appears to be a normal operating characteristic of this vehicle. This problem occurs when the radar has no feedback due to what they refer to as barren conditions. Once the radar receives feedback the system returns to operating normally. I understand your concerns and frustrations, however, we cannot repair a vehicle that is operating as designed.
